"An optimization oversight in the original AccurateRip checksum algorithm results in an unintended loss of accuracy: about 3% of the audio data is not counted in the checksum at all. The left channel's samples are fully included, but in a 65,536-sample cycle, half of the right-channel samples are treated as if they're missing anywhere from 1 bit to all 16 bits."

AccurateRip check sum calculation has a serious flaw that means that errors can go through without AccurateRip noticing it ? It seems like the accuracy is around 97%. And what about ignoring the 5 blocks from the beginning and end of a track ? What if there are errors ? Not detected ?

Re: How accurate is the AccurateRip ?

And if your optical drive supports C2 error checking, that can be used in any case when using dbpa and accuraterip. This is not an either or situation. But do keep in mind that many (most?) drives that report having C2 error checking, don't actually implement C2 correctly and can let errors pass. Accuraterip is head and shoulders above any other method of confirming a bit perfect rip. And it is used by rippers other than dbpa (EAC for example).
